Ruby readline LoadError

The following error seems to be a common problem with many different fixes on the net. I ran into it today with Rails3/Ruby1.9 installed with RVM.

/usr/local/rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': no such file to load -- readline (LoadError)

I found a nifty web site that has a long list of the problems, how they were caused and resolved. Check it out here

Although none of them really helped resolve my issue. I resolved mine by running the following commands

$ sudo apt-get install openssl libssl-dev libreadline5-dev zlib1g-dev
$ rvmsudo rvm remove 1.9.2 
$ rvmsudo rvm cleanup all
$ rvmsudo rvm  install 1.9.2 

Note only use rvmsudo if rvm wasn’t installed using the root account. If it was just use rvm instead.
